But overall, I feel that it's a topic that people talk about before they understand what Ki is.
Of course. By interest lots of people want to know what it is. So they will read about it, and talk about it.
And because it's something not easily explainable, the will talk even more about it.
They have been talking about God since there was a Jesus, and God won't ever be explained (scientifically). If you want people only to talk about God when they understand what it is, only Jesus would be able to talk about it.
So what I want to say is that beginners can also talk about it (Ki), there's nothing wrong with it if they're interested and dedicated to learn about it.
